SPOKE-TENONING MACHINE.

scares.

To all whom, it may concern:

Be it known that I, GUS AVERY, a citizen of the United States, residingat South Bend, in the county of St. Joseph and State of Indiana, haveinvented certain new and useful Improvements in Spoke-Tenoning Machines,of which the following is a specification.

This invention relates to spoke tenoning machines.

One object of the invention is to provide a spoke tenoning machineembodying such characteristics that the carriage which carries themechanism for operating the tenoning tool may be raised and lowered, asde sired, and wherein the carriage may have a forced feed in thedirection of the wheel so that the operator of the machine has to payattention only to the tenoning mechanism operating means.

Another object of the invention resides in the provision of acomparatively simple, inexpensive, durable and efl'icient machine fortenoning spokes of wheels and embodying among other characteristicsmeans whereby the carriage and its tenoning element may have a forcedfeed operation and means whereby the carriage may be moved automaticallyagainst the forced feed movement.

A still further object of the invention is to simplify the constructionand arrangement of the parts of the devices now commonly used for thepurpose of tenoning spokes of wheels.

With the above and other objects in view, the present invention consistsin the combination and arrangement of parts hereinafter more fullydescribed, illustrated in the accompanying drawings, and particularlypointed out in the appended claims, it being understood that changes maybe made in the form, proportion, size and minor details withoutdeparting from the spirit or sacrificing any of the advantages of theinvention.

In the drawings :-Figure 1 is a side elevation of the invention. Fig. 2is asectional view through the upper and lower tracks upon which thecarriage of the machine is operated, illustrating particularly the meansfor adjustably supporting the carriages to show their operativeconnection with the tracks. Fig. 3 is an enlarged longitudinal sectionalview of the invention. Fig. 4 is a top plan view. Fig. 5 is an endSpecification of Letters Patent.

View. Fig. 6 is a plan view of the lower track upon which the carriageoperates. Fig. 7 is an enlarged detail View illustrating the lockingmeans to hold the carriage against the action of the force-feed for thecarriage.

Referring now more particularly to the accompanying drawings, thereference character 1 indicates a frame provided with suitablesupporting legs 2.

The character 3 indicates a base upon which the hub 1 of the wheel maybe sup ported for the purpose of disposing the spokes 5 in properposition for tenoning purposes.

In the present invention there is employed a carriage which is movablebackwardly and forwardly and which when released from its lockedposition is adapted to have a forced feed toward the wheel. The carriageembodies U-shaped or channeled sills 1 1 and 15, webs 27 and 28 andspaced links 6 and 7 and 8 and 9. The links 6 and 7 cross each otherintermediate their ends and at their points of intersection they arepivotally connected together at 10, the links 8 and 9 being pivotallyconnected in the same manner. The links 6 and 8 are fixedly secured at12 and 13, respectively, to the sills 14L and 15, with their free endsprovided with lateral rounded offsets forming bearings 16 adapted totravel in the channeled or U-shaped tracks 17 and 1S, fixedly secured tothe frame 1 by means of metallic strips 19 or in any other suitablemanner. The opposite ends of the links are also rovided with lateralrounded offsets 1G acapted to slide in the sills and the tracks.

By virtue of the pivotal connection 10 between the arms 6 and 7 and Sand 9, the carriage may be raised and lowered because of thelaZy-tong-like connection between the sills and the track members, thetrack members being fixed against movement and the sills being permittedto move toward and away from the track members by reason of the linkconnections 6 and 7 and 8 and 9.

Mounted upon the vertically adjustable carriage is illustrated atenoning bit 21 carried by a spindle 22 upon which latter is a beveledgear 23 designed to mesh with a beveled gear 24, mounted upon a shaft25, upon the ends of which latter are secured the operating handles 26.The tenoning bit 21 may be readily removed and a boring or rimming toolor any other tool may be substituted, and it will be understood that thespindle upon which the tool 22 is mounted, together with the beveledgears 23 and 24 and the operating handle 26 are immaterial as regardstheir construction and arrangement, the essential feature of the presentin vention residing .in the carriage and the means for mounting the samefor movement toward and away from the wheel.

Connecting the lower ends of the links 7 and 9 is a connecting web 28,while connecting the lower ends of the links 6 and 8 is a connecting web27, these connecting webs 27 and 28 being provided with apertures 29 and30, respectively, the aperture 30 of the connecting web 28 being screwthreaded for a working fit with the screw threaded inner end of theoperating screw 31, whose outer end is formed at 32 to receive a wrenchto permit of rotation of the operating screw 31, the rotation of whichwill cause the connecting webs 27 and 28 to move toward and away fromeach other according to the direction of the rotation of the screw andaccordingly raise and lower the carriage, that is, move said links ontheir pivots and raise and lower the sills 14L and 15 toward and awayfrom the lower track sections 17 and 18 for the purpose of alining thetool 21 with the spokes 5 of the wheel, as will be readily understood.

J ournaled in the outer ends of the track members 17 and 18 is a shaft33 which is provided with a groove 34: adapted to receive the springs 35secured to the carriage for the purpose of holding the latter outwardlyaway, from the spokes of the wheel against a forced forward feedsuperinduced by a weight 36 connect-ed to which latter is a cable 37passing over a pulley 38 and connected to the downwardly directed arm 39which has connection with the depending arm 40 of the carriage, whereby,when the springs 35 are disengaged from the groove 34 of the shaft 33 bysimply elevating the weighted arm 41 secured to one end of the aforesaidshaft 33 to turn the latter to throw the groove 34 out of cooperativerelation with the springs 35, the carriage will move forwardly towardthe wheel under what may be truly termed a forced feed, as hereinbeforestated. Then the weighted arm 11 is released, its weighted end 42 willthrow the same to its downward position by gravity and consequentlyrevolve the shaft 33 to its normal position so that when the carriage isforced backwardly against the weight 36, the springs 35 willautomatically engage in the groove 34 in the shaft 33.

The character 43 indicates a foot lever fulcrumed at 44 in the support43, 44 and 44 and having its upper end 39 connected at 31 to thedownwardly depending arm 40, which latter is fixed to the carriage, as

already stated, and by virtue of which connection and upon depression ofthe foot lever or treadle, the carriage will return to its normalposition against the action of said weight 36 and cause the springs 35to automatically engage in the groove 34 of the shaft 33, as alreadystated.

By virtue of the forced feed of the carriage all the operator has to dofor tenoning or boring or other purposes, is to operate the handles 26of the tenoning or boring mechanism.
